UFC Legend Georges St-Pierre has incredibly won the UFC Middleweight championship in his first MMA fight in four years.
GSP put brash Englishman Michael Bisping to sleep with a third round rear-naked choke.
Next up for GSP is a huge showdown with Aussie superstar Robert Whittaker, potentially at UFC 221 to be held in Perth.
In the earlier featured bouts, Rose Namajunas captured the Strawweight Championship of the world when she defeated the previously-undefeated 'boggywoman' Joanna Jedrzejczyk, in a stunning upset to rival Holly Holm's win against Ronda Rousey in 2015.
Meanwhile, T.J. Dillashaw won his second Bantamweight Championship in his career, defeating bitter rival Cody Garbrandt via TKO.
